Using the Xcon 18D2 in the 4.2 cubic foot 18 driver sealed test enclosure results in a moderate sized system with good output headroom. The resulting system shape exhibits a rather peaked response shape centered at 50Hz and a roll off to either side and this is despite the use of a shorting circuit to combat inductance inside of the motor. The long throw of the Xcon driver allows for generous peak headroom in the deep bass but the mediocre sensitivity above 80Hz limits the top end bandwidth some. For best results its probably best to operate this system below 100Hz.
